1995 Chevrolet S-10 OBD Port

So are you trying to read codes?If so you you will need a scan tool that will do the in between the obd1 and 2 set up. Some of the actron scan tools does them. Some of the otc scan tools will do them. Let me know what your trying to do.

Update how?Performance with aftermarket programming?You have to be more clear as to what your asking.

Are you sure that computer in your truck doesnt have a removable eprom you can swap?The earlier gm vechiles had them.I did one on my 1992 chevy s-10.

Your not supposed to be able to flash codes out of those that have the obd2 connector on the 95 and down vechiles. See if there is a little door that comes off your computer held in by a screw were you can swap out the eprom?

Looks like you have a removable eprom so you would get a performance eprom to put in your computer.

Your best bet is find a speed shop that does ecm mapping with the truck on a dyno.

Thanks I did know that remember I mentioned that in my first post to you about not all the scan tools wont read those?I have worked on those cars and they actually read out obd2 codes on the scan tools. As far as programing the ecm yourself I wouldnt recommend it especially with a turbo. Thats why I mentioned having the ecm maped they put your truck on a dyno under a load like your driving down the street. They program the ecm to match the engine turbo etc you have for optimum performance.
